About me

I am a grad student in the BUSec group working with Sharon Goldberg and Ran Canetti. My interests include cryptography and multi-party computation, and how best to utilize these in network security. Before I went to Boston University, I majored in computer science and mathematics at Harvey Mudd College. When not working on crypto or netsec research, I can usually be found playing Dungeons & Dragons, or playing Overwatch.

Current Research

I've just started a project about email security! This is only just barely starting, please feel free to talk to me about it.

Older Projects

Proactively-secure Accumulo with Cryptographic Enforcement

At the MIT Lincoln Laboratory, as assistant research staff, I worked in the Secure and Resilient Systems and Technology group within the Cybersecurity and Information Sciences division to assist in the implementation, testing, and release of a library that adds confidentiality and integrity guarantees to the Accumulo database, protecting it against a malicious server or sysadmin. Earlier in the project, I also implemented Oblivious RAM (Path ORAM) for Accumulo.

Quantifying Latent Fingerprint Quality

As a capstone project at Harvey Mudd College, I worked with a team of four students for the MITRE Corporation on a project to design, implement, and test a system that uses image processing and machine learning techniques to evaluate the suitability of crime scene fingerprint images for identification by Automated Fingerprint Identification Systems.

Statistical Testing of Cryptographic Entropy Sources

As a summer undergraduate research fellow at the National Institute of Standards and Technology (NIST), I worked with Dr. Allen Roginsky in the Computer Security Division to improve NIST's statistical tests for entropy sources for use in cryptographic random number generators. I also made adjustments to the process for generating large primes used in cryptography.
